Introduction to HMD60 Series
The duct mounted HMD60 HUMICAPâ Humidity and Temperature Transmitters are designed
for monitoring humidity and temperature in demanding HVAC and light industrial applications.
HMD60 series transmitters provide stable, reliable, and highly accurate (up to ±1.5 %RH and
±0.1 °C (0.18 °F) measurements, and are resistant to chemicals and dust.
HMD60 series transmitter options include two analog output models: HMD62 for measuring
both humidity and temperature, and TMD62 for temperature measurements. Both HMD62 and
TMD62 use 4 ... 20 mA loop powered current output.
Thanks to easy access to electronics also when the transmitter is installed to a duct,
configuration and adjustment can be carried out quickly and conveniently. Available
configuration and adjustment interface options range from physical trimmers and DIP switches
on the transmitter's circuit board to Vaisala Insight PC software for Windowsâ.
